Struct LogState

Source 
pub struct LogState { /* private fields */ }
Expand description

Calculated state for a package log.

Implementations§

Source§

impl LogState

Source

pub fn new() -> Self

Create a new package log state.

Source

pub fn head(&self) -> &Option<Head>

Gets the current head of the state.

Returns None if no records have been validated yet.

Source

pub fn validate( self, record: &ProtoEnvelope<PackageRecord>, ) -> Result<Self, ValidationError>

Validates an individual package record.

It is expected that validate is called in order of the records in the log.

Note that on failure, the log state is consumed to prevent invalid state from being used in future validations.

Source

pub fn releases(&self) -> impl Iterator<Item = &Release>

Gets the releases known to the state.

The releases are returned in package log order.

Yanked releases are included.

Source

pub fn release(&self, version: &Version) -> Option<&Release>

Gets the release with the given version.

Returns None if a release with the given version does not exist.

Source

pub fn find_latest_release(&self, req: &VersionReq) -> Option<&Release>

Finds the latest release matching the given version requirement.

Releases that have been yanked are not considered.

Source

pub fn public_key(&self, key_id: &KeyID) -> Option<&PublicKey>

Gets the public key of the given key id.

Returns None if the key id is not recognized.

Source

pub fn key_permissions(&self, key_id: &KeyID) -> Option<&IndexSet<Permission>>

Gets the key permissions.

Returns None if the key id is not recognized.
